The benefits of an overlay approach for launching SAM framework: Overlays provide a number of interesting functions including search, indexing, relaying, topology characterization, measurement. Integrating awareness of native multicast in to the overlay is another function like these others that a specific overlay can chose to use or not depending on application requirements. Solutions to the problems of overlays in terms of reliability and security can be used for multicast reliability and security perhaps. ------=_Part_64205_27024760.1170098798602 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Content-Disposition: inline

    Meeting Notes
    Scalable Adaptive Multicast RG
    Interim Meeting Jan 11, 2007.

    1. John Buford (Panasonic)

    Overview of problem statement draft
    and the existing technologies available
    (ALM, Overlay multicast, Proxied overlay
    multicast, tunneling with native multicast
    islands).
    An example architecture and some
    operational scenarios.

    1. Jeremy Mineweaser (MIT Lincoln Labs)

    Adaptativity depends on suitable metrics
    and ability to collect these metrics in
    real-time and feedback to the network.


    Discussion:

    KA: Do you think adaptive approach is too complex to be worth the benefit?
    JM: remains to be seen
    KA: We don't really have a one-size-fits-all protocol

    2. Mark Pullen (GMU)

    Unlike commercial ISPs,DoD ISPs have an incentive
    to use multicast to reduce congestion.
    But universal deployment in GIG may not work any better
    than in commercial sector.
    Gaming community can use multicast in different ways
    than DoD since they don't require the real-world fidelity.

    In battlefield, reliability and robustness may not be
    fully achievable.

    We at GMU have a prototype to manage multicast using
    web services in cooperation with Naval Post-Graduate school.

    There is a need for a framework to interoperate
    different mechanisms, a pervasive interoperability should be targeted.
    Need the pieces to interoperate in order to mix and match technologies.
    Would like to see a standardized tunneling mechanism as well.
    Could use the framework for "relative" QoS not absolute QoS.
    Relative QoS is important for military applications.

    3. Keith Ross (Polytechnic)

    P2P Multicast is an IPTV case study
    There are several success stories: PPLive, Coolstream, ppstream
    200K users at 400-800 kbps for Chinese New Years

    What are the challenges?
    - Bandwidth intensive
    - peers dynamic
    - asymetric residential access
    - incentives for redistribution
    - lags among viewers
    - security (pollution, overtaking for DDoS)

    Comparison of two Architectures
    - Push, tree-based designs, eg. ESM from CMU
    - Pull, meshed based designs
       Inspired from BiTorrent
       But with live streaming
      More successful than ESM

    Overview of pull-mesh
     Locate other peers watching same channel
     Establish TCP connection
     Ask neighbors what chunks they have
     Request and receive chunks
     Start media player
     Upload chunks to others

    Presents some measurements of download
     vs upload rate for different users

    Popular and unpopular channels
    Pull-mesh / IPTV is killer application for multicast

    JM: what are limitations?
    KR: free-riding problem, susceptibility to pollution attack
    Audience: what is the performance comparison between pull and push
    KR: coolstreaming paper has analysis that shows the ESM
        is not good under churn
    JB: what about licensed content?
    KR: yes, content provides can see this as another distribution channel


    4. Kurt Tutschku (U. Wuerzburg)

    Challenges on scalable multicast in overlay with mobile networks
    There are several challenges due to mobile nodes in an overlay
      which translate to problems with overlay multicast with mobile
      nodes
    These problems relate to roaming in the native network,
    node performance capability, variation in network connectivity etc.


    5. Wenjun Zeng (U. Missouri)

    Do you plan to consider reliability, congestion control,
       etc., in the design?
    Pull vs push is an important distinction, as made by Keith
    Is there a hybrid of pull vs push?
    E.g., tree-bone based approach

    6. General Discussion

    What about data aggregation for sensor
    data collection (ad hoc wireless networks),
    is there a multicast solution for this case,
    and how does it fit?

    The benefits of an overlay approach for launching SAM framework:
    Overlays provide a number of interesting functions including
    search, indexing, relaying, topology characterization, measurement.
    Integrating awareness of native multicast in to the overlay is
    another function like these others that a specific overlay can
    chose to use or not depending on application requirements.

    Solutions to the problems of overlays in terms of reliability
    and security can be used for multicast reliability and security
    perhaps.

    Meeting Notes
    Scalable Adaptive Multicast RG
    Interim Meeting Jan 11, 2007.

    1. John Buford (Panasonic)

    Overview of problem statement draft
    and the existing technologies available
    (ALM, Overlay multicast, Proxied overlay
    multicast, tunneling with native multicast
    islands).
    An example architecture and some
    operational scenarios.

    1. Jeremy Mineweaser (MIT Lincoln Labs)

    Adaptativity depends on suitable metrics
    and ability to collect these metrics in
    real-time and feedback to the network.


    Discussion:

    KA: Do you think adaptive approach is too complex to be worth the benefit?
    JM: remains to be seen
    KA: We don't really have a one-size-fits-all protocol

    2. Mark Pullen (GMU)

    Unlike commercial ISPs,DoD ISPs have an incentive
    to use multicast to reduce congestion.
    But universal deployment in GIG may not work any better
    than in commercial sector.
    Gaming community can use multicast in different ways
    than DoD since they don't require the real-world fidelity.

    In battlefield, reliability and robustness may not be
    fully achievable.

    We at GMU have a prototype to manage multicast using
    web services in cooperation with Naval Post-Graduate school.

    There is a need for a framework to interoperate
    different mechanisms, a pervasive interoperability should be targeted.
    Need the pieces to interoperate in order to mix and match technologies.
    Would like to see a standardized tunneling mechanism as well.
    Could use the framework for "relative" QoS not absolute QoS.
    Relative QoS is important for military applications.

    3. Keith Ross (Polytechnic)

    P2P Multicast is an IPTV case study
    There are several success stories: PPLive, Coolstream, ppstream
    200K users at 400-800 kbps for Chinese New Years

    What are the challenges?
    - Bandwidth intensive
    - peers dynamic
    - asymetric residential access
    - incentives for redistribution
    - lags among viewers
    - security (pollution, overtaking for DDoS)

    Comparison of two Architectures
    - Push, tree-based designs, eg. ESM from CMU
    - Pull, meshed based designs
       Inspired from BiTorrent
       But with live streaming
      More successful than ESM

    Overview of pull-mesh
     Locate other peers watching same channel
     Establish TCP connection
     Ask neighbors what chunks they have
     Request and receive chunks
     Start media player
     Upload chunks to others

    Presents some measurements of download
     vs upload rate for different users

    Popular and unpopular channels
    Pull-mesh / IPTV is killer application for multicast

    JM: what are limitations?
    KR: free-riding problem, susceptibility to pollution attack
    Audience: what is the performance comparison between pull and push
    KR: coolstreaming paper has analysis that shows the ESM
        is not good under churn
    JB: what about licensed content?
    KR: yes, content provides can see this as another distribution channel
